My overall scientific interest is to better understand the cycling of natural organic matter in the earth's surface, mainly in aquatic environments such as oceans, estuaries, rivers, groundwater, and lakes. A key objective of my research is to elucidate the role that organic matter plays on the global biogeochemical cycles of major elements (e.g., carbon, oxygen, nitrogen). Specific areas of my on-going research include:
Sources, transport and fate of terrigenous organic matter in river dominated margins, including the Gulf of Papua (Papua New Guinea),Gulf of Mexico,Arctic,Southeast U.S. Fluxes and transformations of organic matter in the water column and sediments from upwelling margins such as theCariacoBasin. Climatic and oceanographic reconstructions of Holocene conditions in tropical and temperate ocean margins using organic biomarkers.
